As soon as the Sooners emerged last weekend as the No. 1 team in the first BCS standings of the season, the pundits started talking about the possibility that they would take a fall at some point.

If the Tigers have anything to say about it, that fall will come tonight in Columbia, Mo., in front of a homecoming crowd at Faurot Field.

The Tigers are 0-7 against OU coach Bob Stoops, including high-profile losses in 2007 and 2008 in the Big 12 championship game.

Here’s a closer look at the Big 12 today:

Iowa State (3-4, 1-2) at (22) Texas (4-2, 2-1)

11 a.m., FSN

Will we see the Texas team that defeated Nebraska last week? Or will we see the one that lost two in a row to UCLA and Oklahoma? Coach Mack Brown will be watching closely to see if the Horns are mature enough to play with a purpose against the struggling Cyclones, who have been blown out by a combined 93 points in the past two weeks.

(14) Nebraska (5-1, 1-1) at (17) Oklahoma State (6-0, 2-0)

2:30 p.m., ABC

Only two weeks removed from being a trendy pick to win the Big 12, the Cornhuskers find themselves fighting to keep up with Missouri in the North Division race. The Huskers face a team rolling with the second best offense in the nation in scoring (49.5 points) and yardage (535.3). Cowboys QB Brandon Weeden, RB Kendall Hunter and WR Justin Blackmon would love to extend their joy ride of a season.

Kansas State (5-1, 2-1) at Baylor (5-2, 2-1)

2:30 p.m.

Needing one victory to become bowl eligible for the first time since 1995, Baylor moves into a three-game stretch against Kansas State, Texas and Oklahoma State, the latter two on the road. After that, it’s Texas A&M and Oklahoma, both at home. Baylor, averaging more than 500 yards per game the past three games, can strike quickly. Kansas State will try to grind it out and consume clock.

Texas Tech (3-3, 1-3) at Colorado (3-3, 0-2)

2:30 p.m.

Texas Tech coach Tommy Tuberville is hearing it from the alumni. In his first year as head coach of the Red Raiders, following the popular Mike Leach, Tuberville is in desperation mode. After losing three of his last four, he faces road games against Colorado and Texas A&M. The Red Raiders must plug the gaps in a defense that has given up 52, 38 and 34 points in the past three weeks.

Texas A&M (3-3, 0-2) at Kansas (2-4, 0-2)

6 p.m., FSN

The Aggies already are headed downhill after three consecutive losses. They don’t want to risk falling off a cliff with a loss today to the Jayhawks. That’s not likely to happen. Despite A&M’s woes, the Aggies have talent that should overwhelm the Jayhawks. The Jayhawks, routed by Baylor and Kansas State recently, haven’t tackled anyone this month.

(3) Oklahoma (6-0, 2-0) at (18) Missouri (6-0, 2-0)

7 p.m., ABC

The key to tonight’s game might revolve around on how OU can handle the Missouri defense. Missouri is ranked second in scoring defense in the nation. The Tigers sacked A&M’s Jerrod Johnson seven times last week in a 30-9 victory at College Station. This week, Missouri pass rush specialist Aldon Smith is expected to be back in the lineup after missing three games with an injury. The Sooners are rolling after a 52-0 victory over Iowa State.
